To be honest I doubt it, but it will decrease the interest in bitcoin in general. I would still probably see bitcoin being used illegally like how drugs are used illegally.
It isn't going to happen anyways, if they wanted to stop bitcoin from growing, why didn't they regulate it when bitcoin was $20,000?
Most people also know about it now and know how to use it for the most part, so I don't think bitcoin isn't going anywhere.
